SNATCHl-BLOCK.

SEECIFIGATION forming part of Letters Patent No. 672,407, dated April16, 1901.

Application filed January 7 1901. Serial No. 42,306. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM J. Houses, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new. and useful Improvements inSnatch-Blocks, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements insnatch-blocks; and the invention consists in the construction andcombination of parts, as shown and described, and particularly pointedout in the claim.

The principal object of the invention is to construct a snatch-blockwherein the strap is made integral with an enlarged headpiece, wherebythe strain on the snatch-block is equally distributed.

Another object of the invention is to simplify the construction of theblock in general, and thereby increase the efiectiveness and d urabilityof the same.

In describing the invention in detail reference will be had to theaccompanying drawings, forming a part of this specification, and whereinlike n umerals of reference will be employed to designate like partsthroughout the several views, in which-- Figure l is a side view of myimproved snatch-block. Fig. 2 is a front view thereof, and Fig. 3 is avertical sectional view of the same.

In the drawings, 1 denotes one of the cheekpieces and the numerals 2 3the two sections which comprise the opposite cheek piece. Thesecheek-pieces are spaced apart by means of a block 4, placed between thesame at their lower ends and secured in position by a rivet or bolt 5,passing through both cheek-pieces, through the block at, and through thestrap of the block.

A strap 6 is partially countersunk in the outer face of the cheek-piece1, this strap at the upper end of the cheek-piece 1 being onlarged andextending across the Widthof the block forming a head-block 7, in whichis swiveled an ordinary hook 8. The cross-head 7 terminates at its freeend in a pin 9, which is provided with an eye to receive a book 9,pivotally mounted on the hasp 10, that is rigidly secured to the outerface of the section 8 of the cheek-piece. This hasp is provided with aneye to receive the pin 9 of the cross-head and at its lower end ishinged to the upper end of the portion of the strap that passes up alongthe outer face of the section 2 of the cheek-piece.

The pulley-sheave is mounted between the two cheek-pieces on an axialpin 11, which passes through the strap and the two cheekpieces and maybe secured in position by an ordinary key-pin 12, so that the axial pinmay be removed when desired. The upper end of the section 3 of the onecheek-piece is beveled, as shown at 14, so that as this section 3 andthe hasp are swung upwardly into closed position the section 3 willreadily enter under the head-block 7, the movement being limited by theclosing of the base of the section 8 upon the top of the section 2 andby the engagement of the hasp with the shoulder of the cross-head 7 atthe. base of the pin 9. The cheek-pieces are usually made of wood inorder to lighten the block to as great an extent as possible, and inorderto prevent splitting of these cheek-pieces I preferably insertrivets through the same, as shown at 15.

I desire to call particular attention to the construction of thehead-block integral with the strap and the dispensing with thespacing-block which is usually employed at the upper'end of thecheek-pieces, where these cheek-pieces in snatch-blocks are constructedof wood. Where this upper spacing-block is employed, the riveted head ofthe hook is hidden from view, and as this is always the first part ofthe block to Weaken it is impossible to see at a glance whether thishead has headed end of the swiveled hook may be readily seen either whenthe rope is upon the sheave-pulley or removed therefrom, as will bereadily apparent, and a greater space is provided between the cross-headand the top of the cheek-piece section 2 for the insertion of the ropeor cable than in the usual construction of devices of this nature.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a device of the character described, a pair of cheeks, one of saidcheeks being in two parts, the lower of said parts being rigidly securedto the opposite cheek-piece, the upper of which parts has aninwardly-beveled end, a block for spacing said cheek-pieces apart, astrap made in two parts secured to the outer face of the saidcheek-pieces, aheadblock of greater thickness than said strap madeintegral therewith, a pin made integral with said head-block, said pinhaving formed therein an aperture, a hinge connection between the twoparts of the said strap, one of said parts having an opening formedtherein, a pivoted hook mounted on said part, a sheave mounted betweensaid cheek-pieces, and a swiveled hook on said head-bl0ck. y

In testimony whereof I affix my signature in the presence of twowitnesses.

WILLIAM J. HOUSE.
